高(gao)壓(ya)集中(zhong)補(bu)(bu)償(chang)是(shi)指將并聯電(dian)(dian)(dian)容器(qi)組直接裝(zhuang)在變(bian)電(dian)(dian)(dian)所(suo)的6～10KV高(gao)壓(ya)母線上的補(bu)(bu)償(chang)方(fang)式(shi)。高(gao)壓(ya)集中(zhong)補(bu)(bu)償(chang)的優點：適用于(yu)用戶遠離變(bian)電(dian)(dian)(dian)所(suo)在供電(dian)(dian)(dian)線路的末端，用戶本身又有(you)一定的高(gao)壓(ya)負荷(he)時，可(ke)以減少對電(dian)(dian)(dian)力系統(tong)無(wu)功(gong)的消耗并可(ke)以起到一定的補(bu)(bu)償(chang)作用;補(bu)(bu)償(chang)裝(zhuang)置(zhi)根(gen)據負荷(he)的大(da)小自動投切，補(bu)(bu)償(chang)效益(yi)高(gao)。

光纖補償(chang)模組(zu)的(de)(de)成因、性質及對(dui)其(qi)進行的(de)(de)補償(chang)

把(ba)電(dian)容器接(jie)在(zai)交流電(dian)網中(zhong)(zhong)，它在(zai)一周(zhou)(zhou)期內上半周(zhou)(zhou)吸(xi)收的和下半周(zhou)(zhou)釋放的電(dian)功(gong)率相等，這(zhe)就是(shi)容性無功(gong)功(gong)率。在(zai)同一電(dian)路中(zhong)(zhong)若(ruo)將電(dian)感與(yu)電(dian)容并接(jie)在(zai)一起(qi)，就能進行功(gong)率補償(chang)，便能夠提高功(gong)率因數，減(jian)少(shao)(shao)電(dian)網輸送的無功(gong)電(dian)流。線(xian)路載流減(jian)少(shao)(shao)了(le)，線(xian)損(sun)也(ye)隨之減(jian)少(shao)(shao)。

低(di)(di)壓(ya)(ya)分(fen)散補(bu)償(chang)就是(shi)根(gen)據個別(bie)用電(dian)(dian)(dian)設備對無(wu)(wu)功(gong)的(de)(de)需要(yao)量，將單(dan)臺或多臺低(di)(di)壓(ya)(ya)電(dian)(dian)(dian)容(rong)器(qi)組，分(fen)散地安裝在用電(dian)(dian)(dian)設備附近，以補(bu)償(chang)安裝部位前邊的(de)(de)所(suo)有高低(di)(di)壓(ya)(ya)線路(lu)和(he)變(bian)壓(ya)(ya)器(qi)的(de)(de)無(wu)(wu)功(gong)功(gong)率。其(qi)優(you)點是(shi)用電(dian)(dian)(dian)設備運(yun)行時，無(wu)(wu)功(gong)補(bu)償(chang)投入，用電(dian)(dian)(dian)設備停運(yun)時，補(bu)償(chang)設備也退(tui)出，可減少(shao)配電(dian)(dian)(dian)網和(he)變(bian)壓(ya)(ya)器(qi)中的(de)(de)無(wu)(wu)功(gong)流(liu)動(dong)，從(cong)而減少(shao)有功(gong)損耗；可減少(shao)線路(lu)的(de)(de)導(dao)線截面及變(bian)壓(ya)(ya)器(qi)的(de)(de)容(rong)量,占(zhan)位小。缺點是(shi)利用率低(di)(di)、投資大,對變(bian)速運(yun)行，正反向運(yun)行，點動(dong)、堵轉、反接制(zhi)動(dong)的(de)(de)電(dian)(dian)(dian)機則不(bu)適應。
